Original Filed Sept. 27, 1928 2 Sheets-Sheet 2 v saw INVENTDR HTTEIRNEY Reissued Nov. 25, 1930 "UNITED STATES PATENT-OFFICE CHARLES W. HALLER, OF WHEELING, WEST VIRGINIA, ASSIGNOR TO WHEELING BRONZE CASTING COMPANY, OF WHEELING, WEST VIRGINIA, A CORPORATION OF WEST VIRGINIA Original No. 1,711,054, dated This invention relates broadly to pickling crates, and it has for its primary object to provide a crate for the'pickling'of metal plates and sheets wherein a plurality of individual and readily separable and replaceable partitions constitute the separators or division walls between adjacent pack-receiving compartments.

A further object is to provide a crate of the character mentioned composed ofnumerous parts which are rigidly secured 1n place in such manner that but few threaded parts are presented, and in which such threaded parts as are used are so located that they are not likely to become corroded so as to require frequent renewals.

A still further object is to provide a pickling crate in which the arts most likely to be injuriously affected y the acids of the pickling bath are readily renewable at relatively small cost and without weakening the crate structure.

Another object of the invention is to provide a crate having compartment partitions so constructed as to prevent or lessen injury to the sheets of the packs or bundles in the several compartments by protrusion of a portion of any sheet outside the compartment in which it has been placed. I

Other important objects will hereinafter be made apparent. v

In describing the invention in detail, reference is herein had to the accompanying drawings, in which g Figure 1 is a side elevation of the invention' Figure 2 is a top plan'view of the same;

Figure 3 is an end elevation;

Figure 4 is a side elevation of a grid, detached;

Figure 5 is an end elevation of the same;

Figure 7 is an enlarged detail view, partly in section, showing the spacers between the up r ends of the grids.

eferring to said drawings, 1 designates the side members, 2 the end members, and 3 the cross members of a cast metal base which is preferably made in a single piece. Pro- PICKLING CRATE April 30, 1929, Serial No. 308,782, filed September 27, 1928. Application for reissue filed March 26, 1930. Serial No. 439,232.

vided at appropriate points in each of the side members 1 below the level of the under sides of the cross members 3, or between the ends of adjacent cross members, is a plurality of openings 4, two such openings hav-v ing rectangular form being herein shown. Sald openings 4 have received therein the opposite end portions of the transversely disposed connecting members 5 of two substantially U-shaped' lifting bars 5. Said bars, which are substantially rectangular in cross section, have their parallel members 5 rismg vertically to a suitable height and carrylng at or adjacent to their upper ends a suitable bracing structure 6, the latter being herein shown as rectangular in form.

Parallel transverse rods 7 have their ends mounted in the parallel members 5 of the lifting bars, and mounted on said rods are the suspension members 8 of a plurality of grids 8 and 9 which constitute partition walls or separators whereby the crate is divided into a plurality of parallel compartments, such compartments being designed for the reception of packs or bundles of sheets or plates which are to be pickled. Eyes 10 provided in-the suspension members 8 receive the rods 7 therein, while tubular spacers 11 mounted on said rods between adacent grids serve to maintain the latter in spaced relation.

Formed on the lower edge of each grid 8 and 9 is a plurality of suitably located depending lugs 12 having therein eyes 13 through which are directed transverse rods 14, the lugs of adjacent grids being maintained on said rods in spaced relation by means of tubular spacers 15 similar to the spacers 11. The lugs 12 of the opposite outermost grids are snugly seated in recesses or seats 16 provided therefor in the top urfaces of the side members 1 of the base, Nuts 17 on the ends of the rods maintain the parts in their proper relations. v

' Each of the outermost grids 9 has formed thereon, preferably as an integral part thereof, a horizontally disposed outwardly projecting ledge 18 provided with a plurality of suitably arranged holes 19 designed for the reception of the downturned ends 20 of two transverse rods 20 whereby is limited the extent to which sheets or packs ma be introduced within the compartments 0 the crates from the opposite ends. I

It is to be noted thatthe grids are removable, thereby to facilitate the removal and replacement of any grid or grids which may become damaged. Further, it will be noted that any of the various parts of the structure, as the lifting bars 5, the rods 7 and 14, the spacers 11 and 15, and the bracing structure 6 may be readily replaced as required. This is particularly desirable in view of the fact that the parts, particularly those which are exposed alternately to the air and to the acid of the pickling bath rapidly deteriorate requiring occasional renewals.

It is to be further noted that the grids constituting the inner partitions 8 and the outer partitions or walls 9 are so formed as to prevent or lessen the protrusion of a portion of a sheet outside the compartment in which it has been placed. Vertical posts, as heretofore used, permit a flexing of the sheet so that a portion thereof bulges outside the compartment in which it has been placed. In the final, or white pickling of sheets after final rolling, this tends to produce bending, nicks, or marks in the sheets where they have contacted the posts. The nicking or marking so produced constitutes a serious injury to the sheet. The partition structure herein disclosed avoids this disadvantage.

\Vhat I claim is:

1. A sheet ickling crate comprising a base,

a plurality o integrally cast extending upwardly from said base, each of said grids comprising a plurality of horizontally disposed bars and a plurality of vertically disposed bars lying all in the'same plane, said grids being attached to the base in mutually spaced arrangement to provide perforate sheet'confining walls giving both vertical and lateral support to the faces of the sheets. 2. A sheet pickling crate comprising a base, a plurality of integrally cast grids extending upwardly from said base, each of said grids comprising a plurality of intersecting bars lying in the same plane, said grids being attached to the base in mutually spaced arrangement to provide perforate sheet confining walls giving both vertical and lateral support to the faces of the sheets.

3. A sheet pickling crate com rising a base, side members, upper tie mem ers' interconnecting said side members, and a plurality of grids extending upwardly from said base; each of-said grids, comprising a plurality of intersecting bars and members for attaching the grid to the'base and to the upper tie members, the grid as a whole being cast in a single piece withall the bars lying in the same plane. 4. A sheet pickling crate comprising a base, side members, upper tie members interconnecting said side members, and a plurality of grids extending upwardly from said base; each of said grids comprising a plurality of horizontally disposed bars, a plurality of vertically disposed bars, and members for attaching the grid to the base and to the upper tie members, the grid as a whole being cast in a single piece with all the bars and the attaching members lying in the same plane.
